Seedance 1.5 Pro AI Video Generator

Transform text prompts into fully synchronized video and audio. Supporting outputs in 480P and 720P, the model generates 4 to 12-second clips at 24fps, ensuring smooth motion and natural sound alignment purely from textual description.

Define your visual style, composition, and character appearance using a single starting frame. The model extends your static image into fluid motion with synced audio (up to 720P), maintaining strict visual consistency across the entire sequence.

Achieve precise narrative flow by specifying both the first and last frames. This dual-frame conditioning ensures the generated video bridges two visual points seamlessly, providing stable 24fps output ideal for transitions and specific plot movements.

By generating audio and visuals in a single pass, Seedance 1.5 Pro guarantees accurate lip-syncing, precise timing, and emotional rhythm. This unified pipeline eliminates the 'uncanny valley' often seen in decoupled generation methods.

Create structured stories effortlessly. Across multiple shots, the model preserves character identity and scene context, supporting cinematic sequences from 4 to 12 seconds. This consistency is vital for long-form content creation.

Moving beyond cascaded generation, Seedance 1.5 Pro synthesizes video and audio signals within a single transformer model. This architecture drastically improves lip-sync accuracy and rhythmic alignment, removing the need for external alignment tools.

The model utilizes a unified multimodal framework where audio and visual tokens interact during the generation process. This deep interaction strengthens temporal alignment and semantic consistency across diverse input tasks.

Trained on a curated dataset emphasizing motion clarity, acoustic realism, and cinematic aesthetics, the model utilizes rich annotations to deeply understand scene context, physics, and intent.

Through supervised fine-tuning, audio-visual RLHF (Reinforcement Learning from Human Feedback), and inference acceleration, Seedance 1.5 Pro delivers high-speed generation without compromising quality, making it ready for real-world production pipelines.

Enhanced motion priors allow for more deliberate camera movements and character acting. The model can distinguish between subtle emotional micro-expressions and grand dynamic actions, giving directors fine-grained control over the performance.

The model natively generates speech, background scores, ambient sound, and foley effects alongside visuals. All elements are aligned at the millisecond level, ensuring lip movements match spoken words and sound effects match on-screen actions.

With superior control over motion range and rhythm, Seedance 1.5 Pro captures fine-grained nuances—from micro-expressions to dramatic camera sweeps—imbuing generated scenes with film-level narrative impact.

The model handles complex monologues and multi-character conversations with ease. It supports Mandarin, English, regional dialects, and various other languages, delivering natural prosody and authentic conversational texture.

Creators gain granular control over style, composition, and effects. Whether using text prompts or image references, the model follows complex instructions to deliver reliable, consistent output that reduces iteration time.

Native support for various visual styles and effects allows creators to trigger specific aesthetics (e.g., anime, film noir, glitch art) directly through prompts, facilitating rapid creative experimentation.
